Most of the dogs are various degrees of Siberian and Malamute, with a dash of other breeds.

several of the purebred groups, after many years of criticism [much of it justified] that they were breeding only for looks and not for good health, good temperament, or preserving any of the working qualities of the original breed, established groups to come up with titles and contests and so forth that encouraged breeding dogs that besides being beautiful could do whatever their ancestors had been bred for.

the akc sleddog breeds all did a pretty good job of instituting some programs, and long-distance, high-speed, sled-pulling races like the yukon quest and the iditarod are similar to the work that siberians were originally bred for, so i’m always glad to see them in these races.
